As will be discussed in more detail below, all energy sources (such as, Vib.) in a working group are made can to carry out operating and can working independently of one another independent of central recording unit according to method of operating of the present disclosure.As used herein, term " scrambler " refers to register system (such as, the controller 202 of Fig. 2), and term " demoder " typically refers to source (such as, the source 206 of Fig. 2).
Referring now to Fig. 3, show a part for the system for acquiring seismic data 300 (it can be similar to those system for acquiring seismic data above-mentioned) that can independently operate.System 300 can comprise energy source 302 (such as, vibroseis energy source) and controller 304.Each energy source 302 can involving vibrations device controller (demoder), wireless communication system, gps receiver and autonomous mode firmware/software.Should point out, any amount of energy source 302 can be disposed in place.The seismic energy source of " working group " can comprise the source of any type described above.Working group can be made up of one or more working crew.Each working crew can comprise one or more energy source 302.Working group can also comprise one or more energy source scrambler (such as, controller 304).Scrambler 304 may be used for realizing and the communication of energy source 302 and event-order serie.Each scrambler 304 can be connected to realize in suitable message handler, for realizing and the control software design of the operation of co-ordination group.
Controller 304 can comprise the signal conditioning package being programmed for autonomous mode order and quality control.Controller 304 realizes autonomous mode working rule, and can programme with configuration parameter and source performance and location database.Controller 304 can be Hosted Software and can carry out with the working group in operating energy source 302 laptop computer that communicates, or can be connected to each demoder in this locality.
Each energy source 302 operates independently.Such as, when seismic operations will be carried out, the vibrating mass of energy source 302 as the operator of energy source 302 instruct through by by the mineral reserve sought.It stops when needed, and performs one or many scanning.After each scanning, scan service (PSS) message after storing.This PSS message comprises when scanning correct time when starting, the position of energy source 302 and the summary of vibrator performance.PSS message comprises the field identifying PSS message uniquely.This storage is different from any storage of the class likelihood data produced during non-autonomous operation completely.
Perform scan at every turn time, Vib. signature signal data can be obtained, and make these Vib. signature signal data can for the applications that will be recorded.Received GPS message and the PSS message that is used for scanning also are sent to external record application.In one arrangement, each energy source 302 Vib. demoder by receive be addressed to it any autonomous operation message, these message are decoded and make response.In a kind of scheme, there are four the basic messae 308:(i that may be used for the working group in management energy source 302 in autonomous mode) red/green order, it can send to working group or independent unit; (ii) reply, it comprise current state (such as, red/green), ID that mistake, position coordinates, performed the last time (latest) are scanned; (iii) scan service (PSS) afterwards, it comprises the position of energy source performance data, correct time that scanning starts, Vib.; And (iv) PSS asks, it can send to each Vib..
Each Vib. demoder can automatically be switched to autonomous operation pattern when receiving any autonomous operation message, and no matter whether this autonomous operation message is addressed directly to it.As safety or measures of efficiency, this message can comprise " the working group's numbering " that make not operation working group can ignore this message.In one embodiment, " green glow " means that seismic operations can start, and " ruddiness " means that seismic operations will temporarily stop.
In autonomous operation, whole working group has state, or is green glow state, or is ruddiness state.Independent Vib. also has green glow or ruddiness state.Do like this is make it possible to the independent Vib. of order suspend due to various erroneous condition.In order to make independent Vib. carry out vibroseis operation, independent Vib. and working group must all be in green glow state.According to the needs being applicable to user-defined condition, can due to various situation, automatically or the manually autonomous operation of the Vib. that temporary suspends is independent, described situation such as, the quality of GPS is unacceptable, will retrieve too many data record, ineffectually other Vib.s contiguous, lack rule wireless communication, the poor performance of Vib., environmental baseline difference (wind is too large, other flows are too many).
If central recording unit (if existence) decommissions, then operator can break-off group operate, until register system is run again.When in autonomous mode, prevent Vib. from making response to the order used under the operation of non-autonomous pattern.In addition, when the demoder of the seismic origin 302 is not in green glow state, prevent them from scanning, that is, they can not produce the energy entered in ground.
Operator uses controller 304 to come first by giving working group by ruddiness message, working group to be set to autonomous operation pattern.Each Vib. returns the response message for ruddiness message.This response message comprise the ID of response unit, the ruddiness state of Vib. confirmation, it receiving the quality of GPS message, the coordinate of its position and perform in autonomous mode the last time scanning ID.When it is ready, operator can start seismic operations by giving working group by green glow message.Each Vib. returns the response message for green glow message.This response message comprises: the confirmation (if its state can not be become green glow by this unit, then it makes response by ruddiness state) of the ID of response unit, the green glow state of Vib., its quality of GPS message, the coordinate of its position and ID of the last time scanning of performing in autonomous mode of receiving.
Its state is periodically inquired to the demoder in all sources 302 in working group by the autonomous mode function software of controller 304.By each scans I D before received and the Current Scan ID from respective decoder being compared, this program can be determined to need to obtain how many PSS message from demoder.Then this software can start to each demoder request PSS message.This software determines optimal number and the requested order of demoder of the message of once asking.
In the process of these operations, due to wireless communication or other various problems, some PSS message may be lost.In response to this situation, but the list of requested also not received PSS message preserved by this software.Based on periodically, suspend every other request.By again asking each PSS message being listed in loss, loss PSS messaging list is processed.If in response to this request receiving to PSS message, then remove it from loss list.Preserve the counting for such request of each loss message.At every turn when sending request but not receiving response, by this count increments.Once counting is exceeded, just removes message reference from list, and this message reference is charged to hereof.
The mode of operation (ruddiness or green glow) of working group and the mode of operation (ruddiness or green glow) of independent Vib. can be shown in graphic user interface (GUI) on the screen of controller 304.The facility that operator can be provided by GUI checks the details of each Vib. state.Operator can attempt using GUI to change to force the state of any independent Vib..Periodicity poll is carried out to the vibrator units in place.Poll is carried out for following information: current autonomous state and position, PSS message, lose PSS message.In addition, communication system can provide user to produce order, such as changes the order of the state of independent Vib. or whole working group.By poll, mean the information that the existence of the requested confirmation appointed information in source 304 and/or transmission are specified.
The software of controller 304 may be used for regulating communication flows.By using suitable communication flows technology, controller 304 can know when radio has a lot of work to do and when not busy they are.It prevents the affairs that do not complete by other affairs are interrupted from occurring, until Current transaction completes.
Because positional information is included in response message, red/green command messages have perform Vib. position requests increase effect.This response message returns in response to red/green message.In the operation of non-autonomous pattern, there is " master " PSS message, message that it is called as in the industry " scrambler PSS ".Data in this message be used for by Vib. PSS data with by by the physical location associated that is known, that survey in the mineral reserve sought.This position is called as " source point ".Working rule set by client, Vib. may be required to make at each source point place vibration one or many.The each scanning produced at this source point place is called as " energy point " or " EP ".The set of one or more " EP " is called as in " oscillation point " or " VP "." scrambler PSS " message is used for all EP and VP numbering associated, and VP numbering is relevant to physics source point.
In autonomous operation, scrambler PSS can not exist.But before seismic operations starts, the list of all physics source points is known.This source point list is loaded in described software.The position of all Vib.s constantly followed the tracks of by described software by coordinate data existing in response message and PSS message.Described software application sorts the algorithm making it possible to each scanning performed easily be found to nearest source point to source point list.
By following the tracks of the position of Vib. and nearest source point, described software can determine when VP starts (from an EP), and it can determine when VP terminates (terminating with last EP).The scanning each time that then described software can perform for each Vib. produces composite encoder PSS message.The convenient storage of this operation is about all properties data of working group and the report based on these data generation contract requirement (CR).
A kind of exemplary algorithm for sorting to source point makes it possible to perform binary search to the coordinate data be made up of dimension, longitude and height above sea level.Source point list can be tens thousand of or hundreds thousand of.Assuming that such extensive list, expect to find out nearest source point with the minimum use of available computational resources.This exemplary algorithm can comprise the following steps:
In order to sort to list, perform following operation: (i) finds four angles (NE, NW, SE, SW) of list; (ii) produce a point, this point is the NW of the frame outside limited at these four angles.This is " list reference point ", and (iii) determines the distance between each source point and list reference point.This is " reference distance ", and (iv) arranges source point list by reference distance.
When nearest source point must be found, perform following operation: (i) uses new coordinate to calculate new reference distance; (ii) reference distance using this new performs binary search to find with regard to the one group source point of value closest to this new reference distance to the source point list arranged; (iii) by this new reference distance of adjustment (+and-) and from lighting the boundary that this subset list is found in this list of traversal indicated by binary search.This traversal will be carried out forward and backward from starting point.When initial point reference distance reference distance after the adjustment, time outside the actual range between the source coordinate of each source point in last described new coordinate and subset list, traversal will terminate.The minor increment calculated is nearest source point.
Another algorithm may be used for keeping the minor increment between energy source 302.Fig. 3 shows the several distances between source 302 with line 310.Expect to guarantee do not have two sources 302 to operate in the distance nearer than user specified value.Exemplary algorithms can use the message received from source 302 to retrieve the positional information in each source 302.From this positional information, the distance between each source 302 can be determined.Controller 302 automatically or can be sent to one or more sources 302 of temporary suspends seismic operations by the prompting of people by ruddiness message.Once re-establish minor increment, just can use controller 304 that green glow message is sent to these sources 302.
Above signal communication can wirelessly and/or with rigid line be carried out.Communication protocol can be made up of analog or digital agreement or synchronous method.
Term " earthquake-predictive device " means any device used in seismic spread, includes, but not limited to sensor, Sensor stations, receiver, transmitter, power supply, control module etc.Herein open provides with reference to illustrating the specific embodiment of described design and method and process.Such specific embodiment and process are not intended to the scope limiting the disclosure or claim.All amendments like this in the scope of claim and disclaimer are all intended that a part of this disclosure.
